Did Paul McCartney Come Up With Kanye West’s "All Day" In 1970?

Paul McCartney has collaborated with Kanye West on a number of songs recently, including Ye's latest single 'All Day' – a track that features a re-recording of an unreleased song the former Beatle wrote in 1969, which is usually referred to by fans as 'When The Wind Is Blowing'.
Now, footage unearthed by Noisey has revealed that McCartney played the song during an appearance on Parkinson in 1999, explaining to the chat show host that the piece had been inspired by a Picasso painting he saw in the hospital where his daughter Mary was born.
